How to Use this Instruction Manual

Electricity Warning

Assembly and initial operation of the line scan camera must be carried out under dry

conditions.

Do not operate the camera if you notice any condensation or moisture in order to avoid danger

of a short circuit or static discharge!

Risk of High Power Lighting

According to the application, laser or high power LED light sources might be used. These can

affect your eyesight temporarily or even cause permanent damage to the eyes or skin.

Do not look directly into the light beam!

Mechanics Warning

Ensure that the motion device and the scan way is free to move and that no obstacles are in

the way.

Do not place any part of the body in the way of moving parts!

Line scan cameras are mostly used in combination with a motion device such as a translation

stage, a conveyer or a rotational drive, as well as with high intensity light sources.

For assembly close down these devices whenever possible. Beyond that, please consider the

following warnings:

Safety Warnings

Please read the following sections of this Instruction Manual before unpacking, assembly or use

Normally, functions like Shading Correction, signal

modification with a look-up table (LUT) or the definition

of a region of interest (ROI) are implemented in

the grabber board. For special requirements these

functions can be made availabel within the camera,

please contact the Schäfter +Kirchhoff customer

support where appropriate.

The camera is supplied precalibrated, with factory

settings for gain and offset. A readjustment is normally

not necessary.

The successful use of the line scan camera requires

that the complete optical system is properly set up,

especially the location of the illumination, the degree

of focus of the lens and the aperture setting. The most

critical factor is the perpendicular alignment of the

sensor axis either with the object to be measured or the

direction of its relative travel when scanned. For further

guidance see section 4.2 Adjustments for Optimum

Scan Results (p. 15).

The SK line scan camera series is designed for a wide

range of vision and inspection applications in both

industrial and scientific environments. The SK512CSD

is compliant with CameraLink Specification Rev 1.1.

Data acquisition requires that the grabber board

conforms to the CameraLinkTM standard. The grabber

board provides the Start-Of-Scan (SOS) signals

and thereby determines the exposure time and line

frequency of the camera.

CameraLink reads the camera specifications from

configuration files. Prior to the iniatial start-up, the

appropriate camera specific file must be created for the

grabber in use.

Beyond, the configuration program SkCLConfig allows

the full parameterization of the camera settings, such

as gain, offset and pixel frequency, via the Camera-

LinkTM serial port interface. SkCLConfig uses the clser*.

dll driver that is supplied with the CameraLink grabber

board.

For the development of custom applications use the

software development kits released from the grabber

board producers.

Introduction

Instruction Manual SK512CSD shared_SystemRequirements_Specs_ML.indd

1.2 Computer System Requirements

1.3 SK512CSD Line Scan Camera - Specifications

Introduction

The camera must be mounted thermally coupled

so that the acceptable casing temperature is not

exceeded during operation. Therefore applies to the

thermal resistance of the bracket or heat sink:

θamb - θcasing

RthHS ≤

Pcamera

where

RthHS [K/W] = thermal resistance of the bracket or heat

sink

θamb [°C] = ambient temperature

θcasing [°C] = temperature of the camera casing (not

to be confused with the internal camera

temperature that is queried and output

with the request command I32)

Pcamera [W] = camera power consumption

The SK512CSD is compliant with CameraLink

Specification Rev 1.1. It is operated in the "Base Confi-

guration" where the signals are carried over a single

connector/cable.

Power supply is provided by a separate power

connector.

Along with the camera the Schäfter +Kirchhoff confi-

guration program SkCLConfig is delivered. Provided

a clser**.dll driver by the grabber board manufacturer

is available, this program facilitates transferring the Set

and Request commands for camera configuration (see

page 4.1 Camera Control by Commands (p. 12)).

Installation and Setup

Instruction Manual SK512CSD shared_Installation-Mechanic_Axx-BGx_ML.indd

2 Installation and Setup

2.1 Mechanical Installation: Dimensions, Mounting Options, and Heat Dissipation

Casing type AC1

Mounting Options

When mounting the camera, pay attention to the

following:

• Mechanical stability to avoid vibrations.

• Good thermal coupling for cooling the housing.

The power consumption and the maximum

housing temperature of the camera are specified

in section 1.4 - Speciﬁcations.

The best fixing point of the camera is the collar for the

mounting bracket SK5105 (available as an accessory).

Four threaded holes M3x 6.5 mm provide further

options for customized brackets.

The length and weight of the optics might be beyond

the capability of the standard mounting bracket

SK5105. For this purpose, a second mounting bracket

type SK5105-2 to hold the tube extension ring(s) is

more appropriate.

Optics Handling

• If the camera and the optics are ordered as a kit,

the components are pre-assembled and shipped

as one unit. Keep the protective cap on the lens

until the mechanical installation is finished.

• If you must expose the sensor or lens surface,

ensure the environment is as dust-free as

possible.

• Gently blow off loose particles using clean

compressed air.

• The sensor and lens surfaces can be cleaned with

a soft tissue moistened with water or a water-

based glass cleaner.

The differential LVDS signals X0-X3 and XCLK are reserved for the transmission

of high-speed video data from the camera to the grabber board. The video data

is transmitted using numerous serial channels simultaneously, according to the

protocol for the channel link chipset from National Semiconductor.

The CameraLink standard defines the names of the pixel signals, the description of

the signal level and the pin assignments and pinout of the chip.
